Androstane carbothioic acids of the formula: ##STR1## wherein R.sup.1 represents a hydrogen atom, a hydroxy group in the .alpha.-configuration, a methyl group which may be in either the .alpha.- or .beta.-configuration, or a methylene group; R.sup.2 represents a hydroxy or protected hydroxy group in either the .alpha.- or .beta.-configuration or an oxo group; R.sup.3 represents a hydrogen, bromine, chlorine or fluorine atom; or R.sup.2 and R.sup.3 together represent a carbon-carbon bond or an epoxy group in the .beta.-configuration; R.sup.4 represents a hydrogen or fluorine atom; and the symbol represents a single or double bond and the salts thereof are useful as intermediates in the preparation of anti-inflammatory androstane 17.beta.-carbothioate esters. The compounds of formula I are prepared by reaction of a reactive derivative of a 17.beta.-carboxylic acid corresponding to the compound of formula I with hydrogen sulphide or a sulphide or hydrosulphide salt.
公式为:##STR1## 其中,R.sup.1代表氢原子,α-构型的羟基,可能处于α-或β-构型的甲基或亚甲基基团;R.sup.2代表α-或β-构型的羟基或保护羟基,或氧代基;R.sup.3代表氢、
溴、
氯或
氟原子;或者R.sup.2和R.sup.3一起代表β-构型的碳-碳键或环氧基;R.sup.4代表氢或
氟原子;符号代表单键或双键。该化合物的盐在制备抗炎症的17β-羧
硫酸酯雄烷中间体时有用。公式I的化合物是通过17β-
羧酸的反应衍
